用溶胶 凝胶法制备光纤化学传感器测定正己烷中噻吩的浓度 ,在 1 0 .6～ 2 6 5μg/mL浓度范围内与lg(F0 /F) )成线性 ,相关系数为 0 .9984。检出限为 1 0 .6 μg/mL ,该方法的平均回收率为 1 0 5.0± 7.7%。
The concentration of thiophene in n-hexane was determined by the sol-gel optical fiber chemical sensor, which was linear with lg (F0 / F) in the range of 106-665μg / mL with a correlation coefficient of 0.9984. The detection limit was 106 μg / mL. The average recovery of this method was 105.0 ± 7.7%.
